I modified the fairing like this. It rotates the stock windshield forward about 10-15 degrees, which cleans up the airflow a lot. Also, opens up a space behind the windshield, where I constructed a homemade dashboard and mounted a GPS. You could also put things like switches, power outlets, etc, there...

The thing about this modification is you can move the angle of the windshield a few degrees, or all the way to nearly vertical. Compared to what I saw others had done, my change was on the conservative side.

I had a tall windscreen (I think it was +6", not sure), which caused a lot of buffeting around the helmet level. Went to this setup, and I get clean air at the head level, and a wind break at the chest level.
